Depending on the project, the platform for expression will be chosen. Proteins can be expressed in E. coli, Insect cells and mammalian cells. For each of the systems we can do small scale (few ml) as well as large scale (few liters) production. For insect cell expression SF9 and SF21 cells are used for expression of intracellular and extracellular proteins. The cells are grown in suspension cultures in volumes up to 500 ml/flask. We use Baculovirus technology for over-expression of proteins in insect cells.
